I just read this hilarious line in Dawkins’ book on religion. It was mentioned in relation to the visible light spectrum to all the various waves that are out there. He took the analogy a little further and talked about how insects have their "burka slit" a little higher up to see the ultraviolet waves. I’m sure it was the only time a noted scientist has used religious garb to make a point about how species consume waves.
Seeing all the colors in this shot, while being in a famous cathedral in Holland, seemed to make a good occasion for that title.
